DEVICE FORA CLEANING WINDOWS.

omgaan-1- y To all who/m fit'may concern."

Be it known that I, ERNEST H. BROWN, a subject of Great Britain, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improveniente in Devices for Cleaning Windows, tion. Y

'Fhis invention relatesto cleaning. devices Y and is primarily directed for use in connection with carwindows employed in ,the vestibule of a traction car occupied by @the driver r motorman, and the principal object of the invention is to provide a device of this character which may be easily operated by the said driver or motorman while the car is in mot-ion without necessitating the drivers removal from his post or losing his control of the propelling mechanism of the car.

@Vith the above and other objects in View,

the invention resides in the novel construction and arrangement of parts whereby a driver or motor-man' of a car may readily remove the mist, snow, rain or sleet which may contact the window and obscure his View of the track which the car is to traverse.

In the accompanying drawings there has been illustrated a simple and approved design of the invention, and in which,

Figure 1 is a partial front elevation of a car provided with the improvements. Fig. 2 is a sectional view upon the line 2 2 of Fig. 1, slightly enlarged. Fig. 3 is an inner view of Fig.' 1. Fig. 4 is an enlarged Vertical sectional view upon the line 4 4 of F ig.

' 1. Fig. 5 is a side elevation of the carriage.

Fig. 6 is a perspective view of the carriage guide. Fig. 7 is an enlarged sectional view upon lthe line Z-7 of Fig. 1.

In the accompanying drawings the numeral 1 designates a sliding sash usually employed in connection with the vestibules of cars, but it is to be 'understood that the apparatus, hereinafter to be described, is not limited to car windows as it may be eifectively operated upon other window sash'es if desired. The window 1 has its vertical stlles 2, each providedy with suitable openings at their tops and bottoms within which are rotatably mounted suitable pulleys or sprocket wheels'. The pulleys or sprockets are each adapted for the reception of suitable chains or other flexible elements 4. lThe free ends of eachi'of the chains or flexible members 4 are adapted to be received within Specification of Letters Patent. Y Application ined nai-cn a, laos. serial No. 481,058,

of which the following is a specifica-I ".suitable 'eyes carried by a carriage guide` 6 plainly illustrated in detail in Fig. 6 of the.

drawings.

`"The outer facesl of each of the vertical provided with suitable vertically Stiles are arranged toothed racks 7, and these racks are adapted for \engagement with toothed wheels 8,-'9 and 10, carried upon the ends 11 of the carriage 12. Thiscarriage 12 is .adapted to serve as a tral bushing member 13 carried by' the"cen Patented Mar; (1,., 1.910.-`

housing fo`r\the central shaft upon which the toothed wheel is positioned and the, roller members 14 hav l i i ing their outer 4faces coated with cloth or rubberas designated by the numeral 15.'

These roller members 14 as well as the brush .member 13 have their shafts extending a suitable distance away from the endsof the casing and are adaptedfor engagen-ient with the openings 17 'carried by the guide 6. lVhen the shafts are positioned withinthe said guide` the wheels S, 9 and 10 are positioned thereon, thus allowing the casing 11' to extend the full width of the hinge, while the casing 6 may be positioned adjacent the said stiles 3 of the hinge and force the toothed. wheels into engagementwith the toothed racks 7 in a manner which will hereinafter be fully set forth. l

By reference to Fig. 5 of the drawing it will be noted that the carriage 12 comprises a central curved portion within which the brush 13 is housed and extending from each side of this curved portion are small face-s within which the rollers 14 are hou while projecting toward the end of th riage are oppositely disposed inclined mei bers each being provided with a substantially U-shaped rubbing element 1G composed of rubber or the like.

i rFhe guide 6 comprises a substantially rectangular member comprising' a pair of spaced sides,'one of which being provided i :with openings 1T and these sides have their edges inturned `as at 19 so as to provide'a guide Way, which is adapted to contact with suitable frames hereinafter to be fully set forth. The guide members 6 are also provided at their tops and bottoms with suitable Aconnecting elements lupon which the eyes 5 are positioned, thus lleaving a back open portion within which the wheels 8, 9 and 10 are housed.v

' The numeral 18 designates the guide of the device. This guide frame is preferably constructed of some suitable resilient material,

,the'frame 8, 9 and 10 firmly into engagement with the teeth of the rack bar '7. Connected with each of the' flexible elements 4; upon the interior of the vestibule of the ear or like device to which the device is attached is a transverse rod This rod is preferably provided with a centrally arranged downwardly set or handle portion 2t as clearly illustrated in Fig. 2 of the drawing. lilith this arrangement it will be noted that the device may be operated from the interior of the car and that the driver or motorman may retain one hand upon the propelling mechanism vand manipulate the cleaning apparatus with the other and Without Ydanger of losing control of the car.

Having thus fully described theinvention what is claimed as new is:

1. A Window sash having its vertical side rails provided Withl toothed bars, a cleaning device provided with toothed Wheels engaging the toothed bars, said lcleaning device comprising a casing carrying yieldable rollers and ay rotatable brush member positioned intermediate of the rollers, and means connected with the cleaning device, whereby the same is forced resiliently into engagement withv the toothed bars, and means for operat-' ing the device from the. offset side of the sash,

Q. In a ivindoiv cleaning device, the combination with a window frame, a casing extending transverselly of the glass of the frame, said casing having oppositely disposed inclined cdges,' -:il: lc scraping members engagedy Within the inclined portions of the casing, yieldable rollers within the casing, a brush member intermediate of the rollers within the casing. shafts for these rollers and brush members. guide members having vtheir sides provided with openings engaging` the shafts,\\vheels upon the shafts within the guide members, said guide. memcxtending otf- I vertical arms of the guide frames adapted to engage Within the Ways of the guide member. and tiexible membersV secured to both the/top and bottom ofthe guide and extendy ing upon the opposite face ofthe sash, substantially as and for the pur-pose set forth.

3. The combination with a window frame having its vertical stiles provided with toothed racks, resilient guide frames also upon the side stiles and offsetfrom the racks, said frame being provided with upper and lower rollers communicating with the opposite sideof the frame. and adjacent thc ends of the toothed racks, a casing having oppositely inclined longitudinal edges extending transversely of the frame, a flexible element connecting the opposite sides of the rollers and extending upon the opposite face of the frame, said casing adapted for engagement with the resilient guide frames and being provided With rotary cleaning members and end stationary cleaning members, and an operating bar connected With the flexible elements upon the opposite side of the sash.

4. The combination With a sash having its vertical stiles provided with toothed racks and openings adjacent the ends of the racks adapted for the reception o f pulleys, resilient.- otfset guide frames upon the stiles, a casing having a plurality of toothed Wheels provided upon axles extending longitudinally of the said casing, the casing being providi with oppositely disposed beveled longituuinallv extending edges, stationary cleaning mei bers upon the interior ofthe casing adjacent its inclined ends, rotary cleaning members upon the shafts of the casing. guide carriages'engaging the said shafts and the guide frames of the sash and adapted to force the. wheels of the casing into e011-, tact with the racks,- and a fiexible element connected with both the top and bottom of the guide carriage extending over the pulleys of the sash and provided ivith an ott'set comiecting rod, substantially as and for the purpose set forth. v I

ln testimony whereof I affix my signature in presence of two witnesses.
